2^F→grassboy2: 嗯~話說照理來說解出來的碼是什麼樣子呢？10/11 11:47

3^F→grassboy2: 是另一串的 0101 然後不受環境影響每次解都同一組嗎？10/11 11:47

7^F→grassboy2: 喔喔！？一定要知道解碼方式嗎？我想實作出「萬能搖控10/11 17:28

8^F→grassboy2: 器」的程式，我按一個鍵，他學一個鍵，我如果按下同一10/11 17:28

9^F→grassboy2: 顆鍵，他會說這個鍵按過了，按新的鍵，他才學新的鍵10/11 17:29

10^F→grassboy2: 目前手上有支學習型搖控器，似乎也沒有要知道protocol10/11 17:30

11^F→grassboy2: 還是他有其他原理來達成呢？10/11 17:30

12^F→grassboy2: 我那支學習型搖控器是只要把其他搖控器按鈕按一下他就10/11 17:32

13^F→grassboy2: 能錄下來的樣子~10/11 17:32

15^F→grassboy2: 耶逗…http://i.imgur.com/tmjb0m7.png 這是那塊版的10/12 03:09

16^F→grassboy2: 硬體規格降子…所以接收取樣率是 38kHz 降子嗎？10/12 03:10

18^F→grassboy2: 喔喔！查了一下…似乎是 tsop38238 這顆…這有解嗎？10/12 12:43

19^F→grassboy2: http://www.vishay.com/docs/82491/tsop382.pdf10/12 12:56

20^F→grassboy2: 這是他的技術文件？順便問個概念…10/12 12:56

21^F→grassboy2: 世面上家店百百種…但紅外線通訊協定只有不超過十幾種10/12 12:57

22^F→grassboy2: 上面這觀念是正確的碼？10/12 12:57

23^F→grassboy2: (家電)10/12 12:57

7^F→grassboy2:所以有辦法入手這類的 chip 嗎？如果只要一兩塊的話…06/24 19:19

10^F→grassboy2:所以他不像一般電子材料…線接好就可以直接插進去跑了嗎06/25 18:20
